Known as the gas giants even though they have deep layer of liquid.
What are Jupiter and Saturn?
100
This high-pressure storm on Jupiter is a least 300 years old, twice as big as Earth, and swirls counterclockwise.
What is the Great Red Spot?
It has been known to change shape, size, and color.
100
The interiors of the giants are mostly liquid because of this property of the interior.
What is high pressure?
This keeps hydrogen, water, etc. in the liquid state even when temperatures are high.
100
The rings of Saturn are made of these.
What are tiny icy particles and moons in thousands of ringlets?
Mostly water ice, so reflect the sun and are very bright.
100
Why Pluto is no longer considered a planet
What is it failed to clear its orbit?
There are many other objects orbiting nearby in the Kuiper Belt including comets and other dwarf planets (Eris, Haumea, Makemake)
200
Uranus and Neptune are known together by this name.
What are ice giants?
200
These features of Jupiter are caused by alternating east and west winds.
What are the light and dark bands?
Light called zones and Dark called belts.
200
Planets where liquid hydrogen acts like a metal deep in the interiors.
What are Jupiter and Saturn?
This phase is called Liquid Metallic Hydrogen and electrons move about freely.
200
What happens when a moon gets too close to a giant planet (inside the Roche Limit).
What is it is torn apart forming rings?
Gravity causes this.
200
Location of Ceres.
What is the asteroid belt (between Mars and Jupiter)?
It is the only dwarf planet there.
300
Contained in the ice giants that make them more dense than the gas giants.
What are heavy elements (elements other than hydrogen and helium)?
They also contain compounds such as water, ammonia and methane.
300
Home to the Great Dark Spot and other transient storms.
What is Neptune?
Can also observe light and dark clouds on Neptune (as well as Uranus).
300
Materials that make up the cores of giant planets.
What are rock, water and metals?
Likely liquid or possibly solid.
300
These help rings keep their shape through gravitational herding.
What are shepherd moons?
300
One property of Pluto that is different from other Kuiper Belt objects.
What is its atmosphere?
Pluto has a methane atmosphere, while other objects have no atmosphere.
400
Causes giant planets to not be perfect spheres.
What is rapid rotation (less than a day)?
The planets are oblate, meaning fatter near the equator.
400
Planet with band structure similar to Jupiter's but with different colors and chemistry.
What is Saturn?
400
Types of ice found in the "oceans" of Uranus and Neptune.
What are water, methane, and ammonia?
These layers also contain other dissolved gasses and salts.
400
Even though Saturn's rings are almost as wide as the planet, they are extremely ______.
What is thin?
Only about 100 yards thick.
400
One way Eris is similar to Pluto.
What is in the Kuiper Belt?
Also icy and eccentric orbit.
It is more massive than Pluto and lacks an atmosphere.
500
If a planet's obliquity is _______ (small or large), it will not have seasons like earth.
What is small?
For example, Jupiter is only tilted by 3 degrees, so does not experience seasons.
500
Feature of storms seen on Saturn.
What is lightning?
Saturn has infrequent but violent storms.
500
Because they took longer to form out of small far-apart icy bodies, Uranus and Neptune have _________ cores than Jupiter and Saturn.
What is younger?
500
Reason we can not easily see the rings of Jupiter, Uranus, and Neptune.
What is they are made of dark material?
Made of rocky silicates (Jupiter) and organic material (U & N), not ice like Saturn
500
This dwarf planet contains about one-third of the mass of the asteroid belt.
What is Ceres?
It used to be classified as the largest asteroid.
